Apparatus for electrically switching between peripheral devices

An apparatus for electrically switching between peripheral devices for a host device, comprising:

• a first port for connecting to a first peripheral device;
• a second port for connecting to a second peripheral device;
• a sensor for sensing a binary signal sent to the host device from a second peripheral device actively connected to the second port;
• and
• a switch connected between the first port and the host device and responsive to the sensing of a binary signal sent from the second peripheral device for disconnecting the first port from the host device.

A method of switching between peripheral devices for a host device, comprising:

• providing first and second ports through which first and second peripheral devices are coupled to a host device;
• sensing active connection of a second peripheral device to the second port;
• and
• in response to sensing the active connection, disconnecting the first port and thereby the first peripheral device from the host device.
